easy rendering for Rhino in Windows
A true minimum would look like this:
Intel Core 2 Duo 2.0 GHz or AMD equivalent
2 GB RAM
80 GB HD
Open GL Graphics Card
But I expect you are not looking for a true minimum. To optimize a machine for Flamingo NXT there are a few notes:
NXT is affected by the number of CPU cores. The more cores the better. I am a big fan of Quad core machines. I believe there are the best bang for you buck. A rough method estimate of rendering speed can be found by multiplying the number of CPU cores x the Ghz of the CPU. For instance a 4 core x 3.1 Ghz will have a 12.4 score. An 8 core 2.4 GHz machine will have a score of 19.2. The 8 core machine will be 54% faster. This works best when comparing similair chipsets. Roy runs a 12 core machine.
The 2 GB limit of 32-bit machines is currently the biggest limiter to renderings. I would recommend a 64-bit system using Windows 7 and 6-12 GB of RAM. Rhino 5 and NXT will run well in 64-bit.
Graphics card speed does not affect Flamingo NXT. but, of course graphics card speed does affect how fast Rhino feels. Nvidia Quadro cards are my favorite.
I hope this helps.
